Pain under the right shoulder blade: possible causes

People often describe pain under the right shoulder blade as "pulling", "stabbing", or "making it hard to breathe in". The shoulder blade is a flat bone on the chest that is moved by the muscles of the back and shoulder. The source of the pain may be in the shoulder blade itself, in the spine, in the muscles, or in the organs on the right side.

Where pain under the right shoulder blade may come from

Back pain is characteristically nonspecific: in 90% of cases, examinations do not find a physiological cause. A common cause is a strained muscle or ligament. Less common are intervertebral disc disease, nerve compression, and ankylosing spondylitis. Very rarely, back pain is a sign of a fracture, tumor, or infection. Localization under the shoulder blade does not cancel this rule: first the doctor rules out dangerous causes, then looks for a mechanical one.

Pain from the spine and muscles

The spine works like a lever: vertebrae, discs, and facet joints bear the load, and muscles distribute it. Degenerative or traumatic changes in discs and joints cause secondary pain in muscles and nerves, as well as referred pain in bones, joints, and limbs. Pain may be local, radiating, or referred. With a muscle strain, a person often cannot name the event that caused it. In some people with normal imaging, chronic pain persists due to central sensitization: after an injury, sensitivity remains increased.

Pain from internal organs on the right

Diseases and inflammation of the gallbladder, pancreas, aorta, and kidneys can cause referred pain in the back. Tumors of vertebrae, nerve tissues, and adjacent structures also sometimes manifest as back pain. Referred pain is felt not at the site of the pathological process: with pain under the right shoulder blade, the doctor considers that it may come from internal organs and, if necessary, refers the patient for examination. The doctor checks whether there is fever, chills, or chest pain.

Aching and sharp pain: what they may mean

Back pain ranges from dull and constant to sudden and sharp. By duration, acute pain lasts up to 6 weeks, subacute — from 6 to 12 weeks, chronic — more than 3 months. These time frames help the doctor understand whether this is a recent reaction to load or a prolonged process. Sudden severe pain or pain that rapidly intensifies requires an urgent appointment with a doctor.

Pain when breathing: what to pay attention to

If pain worsens with coughing, sneezing, or straining, this is a reason to see a doctor; this sign does not define a separate diagnosis.

Red flags and when to see a doctor

See a doctor if pain under the right shoulder blade does not go away after several weeks, interferes with daily activities, worsens at night, or does not decrease after rest. A reason for a visit is unintentional weight loss, swelling, or a change in the shape of the back. If the pain comes from the upper back, between the shoulder blades, this is also a reason to see a doctor.

• pain does not improve after several weeks;
• pain interferes with work, sleep, and self-care;
• weight loss without trying to lose weight;
• swelling, a lump, or a change in the shape of the back;
• pain is worse at night or does not go away after rest.

When an ambulance is needed

Pain under the right shoulder blade by itself is not a reason to call an ambulance; 103/112 — if it is combined with chest pain, weakness or numbness in both legs, loss of sensation around the genitals and anus, or changes in bladder or bowel function. An ambulance is needed if the pain began after a serious accident or injury.
